Offline Strategy for Securities in TRM

Hi,

I am implementing TRM module. Two companies with TRM module are working now. Now one company will be offline and migrate to Summit.

I have the following questions about securities:

1. What is offline strategy for Securities,ex. for bonds?

2. How to block not due securities from amortization and period end closing transaction in SAP?

3. Can i change status of bonds from active to inactive? How to do it for already settled transction

Would appreciate your help/inputs on this.

Thanks in advance

Roger
